''Phlebopus marginatus'', known as the salmon gum mushroom in Western Australia, is a member of the Boletales or pored fungi and possibly Australia's largest terrestrial mushroom with the weight of one specimen from Victoria recorded at 29 kg (64 pounds). It is an imposing sight in forests of southeastern and southwestern Australia. Initially described as ''Boletus marginatus'' in 1845, and also previously known by scientific names such as ''Phaeogyroporus portentosus'' and ''Boletus portentosus'' it is in fact not as closely related to typical boletes as previously thought. ==Taxonomy== English naturalist Miles Joseph Berkeley initially described ''Boletus marginatus'' in 1845, from the writings and specimens of James Drummond, from the vicinity of the Swan River Colony in Western Australia.〔 Berkeley and Broome described ''Boletus portentosus'' in a report published in 1873 of the fungi of Ceylon, from a specimen with a 25 cm (8 in) diameter cap collected on June 15, 1869. They held it to be related to ''Boletus aestivalis''.〔 Microscopic differences led to it being reclassified; Boedijn noted the shape of its spores, lack of cystidia and short tubes and allocated it to the genus ''Phlebopus'' in 1951.〔 New Zealand botanist Robert McNabb followed Rolf Singer who had determined ''Phlebopus'' was a nomen dubium (though conceding Singer was likely in error), and coined the binomial ''Phaeogyroporus portentosus'',〔 by which it was known for some years. In his 1982 review of the genus, mycologist Paul Heinemann used this latter designation.〔 The generic name is derived from the Greek Φλεψ/Φλεβο- "vein", and πους "foot". Considering the two taxa to be the same,〔 mycologist Roy Watling proposed the name ''Phlebopus marginatus'' over ''P. portentosus'' in 2001, pointing out that the former name predated the latter.〔 He noted specimens across its range conform to the species description, although queried whether a single species occurs over so wide a range. It is in fact not as closely related to typical boletes as previously thought and is, in fact, a member of the ''Sclerodermatineae'' and sister to ''Boletinellus merulioides''.〔〔 ''Boletus brevitubus'', described from ''Cephalocitrus grandis'' and ''Delonix regia'' forests of Yunnan, China in 1991,〔 was placed into synonymy with ''Phlebopus marginatus'' in 2009.〔 A common name in Western Australia is salmon gum mushroom.〔 Common names in Asia include ''hed har'' and ''hed tub tao dum'' in Thailand, or tropical black bolete. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phlebopus marginatus」の詳細全文を読む スポンサード リンク
